I'm a feminist and don't argue for those things. I'm pretty sure the majority of feminists on this board don't argue for this. You've met every single feminist have you? Or you've just seen one on YouTube.
I didn't say every single feminist, did I? If you want see what a strawman is, perhaps look at your own words.
What I said was that some feminists do want these things. Including many who are regulars on this board I'm sure (FYI I've lurked - and occasionally posted - on FWR for the best part of the decade, so I have a fair grasp on what kind of views are represented here). There have been campaigns around things like the gender pay gap. Have you not noticed them?
I believe women should have the right to choose their life path, whether that's getting married, having a big career, having no kids, being a stay at home parent.
I'm not an expert on Peterson. I've watched some of his videos and feel that I understand the basic gist of his thinking. I agree with some of it, disagree with other parts. There's nothing I have seen of his views that make me think he would disagree with what you have written above. He is absolutely all about people taking charge of their lives and finding their own path, as far as I can tell. I suspect he is almost certainly on your side with regards to equality of opportunity.
The more I think about your insistence that equality of opportunity is a strawman though, the more unconvinced I am. I am left of centre politically, and while I don't want absolute equality of outcome, I want greater equality of outcome than we currently have, as I'm sure do many other left wing people. Equality of opportunity alone doesn't do it, because equality of opportunity could mean that one person is a billionaire and one person lives on the street and as long as they both had an equal opportunity to end up in each situation everything is okay. I'm not okay with individuals amassing disproportionate amounts of wealth and I am certainly not okay with anyone to be forced to live on the street. So I do want something closer to equal of opportunity.
So if equality of opportunity is a strawman then I am that strawman, as I suspect are large sections of the political left for the past couple of hundred years.
